Jon, Some of the template upgrades may work for you (I did'nt try them yet). But I have run into the same situation. To work around it I just moved ahead in the geometry and put in another Feed Change to return it to my original feedrate on the last element.
Another trick I learned was to actually use an evaluation instead of direct change. For example using the Feed change option in SC all you can input is a number like 70 IPM. But since I use the same file to generate programs for IPR as well as IPM (depending on machine) and I can change my feed rate in my planner and all Feed changes I put in will be proportional, I use an evaluation like #FEED=(#FEED*2). Following your example I would set my planner to 40 IPM and then insert a Feed change for 70, then go back and modify the Feed change element to read #FEED=(#FEED*1.75) (instead of #FEED=70.), then at the end of that profile insert another feed change and modify it to #FEED=(#FEED*.57) John Morris Kennley Corporation - "Because you want Quality, Now." http://users.erols.com/kennley -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Jon Baker Sent: Friday, January 25, 2002 12:57 PM To: SmartCAM List Server Subject: [mfg-smartcam] Milling question. I use Freeform, but this applies to all of the milling modules. When I use Create-Machine Event-Feed Change to modify a feed rate it works just fine, however from that point in the model forward, it keeps that feed rate. On a part I was just surfacing, I want the first cut to go slower since it is taking a full bite, but then each step over is only .005 so I want that to go faster. What I did, was slow my feed in the jos to 40ipm and after the first element, bump it to F70.0 ipm in the feed change. Then when I pull out of that surface, and start another one with the same tool-step, I would think it would update upon the down feed and profile start, however it doesn't. It keeps the 70ipm rating and runs with it. So, is this a .tmp problem? or a .smf problem, or just one of those things. I am sending my .tmp file along so you can see what I am doing in there too. Thanks for any help.
